Re: Rotella T6 cause scoring to spool valves?
What should make you immediately raise the BS flag is that they said the T6 is too thin. T6 has either 0W-40 or 5W-40. Schaeffers offers up to 30 in light truck, and up to 40 weight in their heavy duty. Weights aren't just assigned randomly. They HAVE to meet certain requirements to be labeled a certain SAE viscosity. So, to say the 40 weight is too thin as compared to a 30 weight, or another 40 weight, just reeks of a dairy...and in case you've never smelled a dairy, it's NASTY! lol
